Heretic

About the game

Heretic answered a simple question with style: what does Doom feel like as sword-and-sorcery? Raven Software, working closely with id on licensed engine technology, cast the player as Corvus, an elf striking back at the undead armies of a serpent rider across crumbling citadels, swamps and cathedral vaults. Crossbows, elemental wands and the phoenix rod stand in for the usual ballistics, and enemy gargoyles dive at you from open skies.

Raven pushed the borrowed engine somewhere new. Heretic added the ability to look up and down, wind currents that shove the player around, and — most influentially — a Tome-of-Power-driven inventory system. Collecting and timing consumable artifacts (invincibility rings, morph ovums that turn knights into chickens, wings that grant flight) layered a resource game on top of the twitch shooting.

The result was more than a reskin: it demonstrated that the emerging FPS formula could host different fictions and deeper systems. Its success set up Raven's darker, more ambitious Hexen a year later and established the studio as the era's premier engine-licensee developer.

Technical notes

Built on a licensed, extended Doom engine: vertical look, ambient wind physics and inventory items bolted onto the sector renderer. The DOS original is the version documented here.
